Validation roster
| Layer | Candidate systems | Use |
| Pre-analysed core | HAT-P-11b, WASP-19b, HAT-P-36b, WASP-52b | Known timing-scatter and spot-contamination cases |
| Stress tests | Kepler-17b, AU Mic b, K2-25b | High-activity or young-star domain-gap checks |
| Timing controls | WASP-4b, WASP-12b, WASP-43b | TTV/orbital-decay and false-positive benchmark cases |
| Reserve benchmarks | HD 189733b, Qatar-1b | Archive-rich activity targets available if a primary candidate fails quality gates |
GJ 1214b remains a JWST atmospheric comparison example in the data-source manifest, but it is not counted inside the
12-system timing-validation roster.
